Fedora 11 QT4 Error? Not Sure

[tfruth]

Downloaded the 3.0.2 rpm for x64 hosts, installed on Fedora 11, ran just fine, everything worked. I installed an XP guest, with Vbox guest additions, and everything worked fine. I shut down my guest and my host.

Got up this morning and VirtualBox won't load. Opened terminal, called up VirtualBox, and got the following:

VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: /usr/lib64/libQtNetwork.so.4: undefined symbol: _?N7QObject11qt_metacallEN11QMetaObject4CallEiPPv

So, to recap, it was working when I shut it off, and now it doesn't.

I'm running kernel 2.6.29.4-167.fc11.x86_64. I know there's a slightly newer kernel, but the nvidia drivers wouldn't compile for it, so I am waiting a few weeks.

I'm running qt-4.5.1-13.fc11.x86_64.

Have you entered yourself (login) in the VBoxusers group?

Since it used to work, along with the error you get, it's a real tricky one. I've seen that error countless times, but there are several solutions for it. The easiest you can try is a full system update. If that doesn't help, you have to search the board here for the error you get. A part of it will surely help, instead of selecting the whole error.
One 'solution' I do remember was to install font-config, but there were users who already had it, or it didn't fix anything for them. Try the Bugtracker too when searching.

Updates for FC11 x64 were recently posted. I applied them and VirtualBox seems to be working. Here are the updated versions:

$ uname -r
2.6.29.6-213.fc11.x86_64
$ rpm -q qt
qt-4.5.2-1.fc11.x86_64
